Harraseeket River

The Harraseeket River is a 3.2-mile-long (5.1 km) tidal river in the town of Freeport within the U.S. state of Maine. It forms a northern arm of Casco Bay.

Several smaller streams flow into the Harraseeket that have their headwaters in Freeport and Brunswick, to include Frost Gully Brook and Kelsey Brook. The Harraseeket embayment joins Casco Bay between Moore Point on its eastern shore, and Stockbridge Point on its western shore, with a small island called Pound of Tea dividing the channel.

The Maine Department of Inland Fisheries & Wildlife includes the Harraseeket in the designated Maquoit and Middle Bay Focus Area of Statewide Ecological Significance that extends from Harpswell Neck to the Royal River in Yarmouth, recognizing a diverse habitat for fish and wildlife including tidal marshes, eelgrass beds and mudflats.

Protected lands open to the public along the Harraseeket include Wolfe's Neck Woods State Park, the Mast Landing Audubon Sanctuary and Winslow Memorial Park.
